SUSPENSION OF VEHICLES.

Application filed .Tune 2, 1922, Serial No.

The invention relates to improvements in vehicle suspension and consists substantially in that a system of joint levers is inserted between the under-frame and the axle of the vehicle so that the changing of the springs is transmitted to the under frame in such a manner that the vertical component of the resultant of the lever system is nearly constant within practical limits for every po- 9 sition of the wheels with respect to the vehicle.

It is clear that by means of a proper arrangement of springs, levers and other orans the variations of spring elasticity can be reduced to the least so that a smooth run- .ning of the vehicle may be secured.

'- pivotally connected lever arms (10) and (8) with two other lever arms (17 and (18) by means of a suitable mechanical expedient by which the movement of the arms 10 and 8 is transmitted to the arms 17 and 18, the latter moving in opposition to the arms 8 :1. ad 10.

The lever arms 10 and 17 may oscillate around the pivots (19) and (20) both fixed to the under-frame. Each arm is provided with a toothed quadrant, both quadrants engaging; one another, consequently if one of the lever arn'is tor instance (10) describes a certain angle of rotation around its own pivot (19) the other arm must describe the same angle around its own pivot (20).

'ihe lower end of the lever (17) is articulated to the upper end of the lever (18).

Lover (10) is connected with the upper end of a lever arm (21), the latter being connected with and subjected to the tension of a spring 22.

The lower ends of levers (18) and (8) oscillate around pivots 23 and 24 fixed to a. support on the axle (25) and said levers are also geared together in the same manner as the lever arms 10 and 17.

By means of the suspension described the movements of the arms (10) and (17) correspond exactly to those ofthe arms (8) 565,353, and in Italy September 22, 1921.

and (18) though taking place in opposite directions, so that the parallelogram of forces constituted by these four arms is allowed to lengthen or to be compressed but in the direction oi the vertical XY. The wheel (26) under the action of spring can freely descend into a depression of the ground but it can be shifted neither -lorwardly or rearwardly relative to the body of the vehicle.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be per formed I declare that what I claim is:

1. In combination, a vehicle body and an axle arranged. thereunder, pairs of links, the links of each pair being pivotally connected with one another and with the vehicle body and said axle, the pivotal connection be tween the links of one pair and the body and axle being displaced with respect to the pivotal connections between the links of the other pair and said body and axle, and means connecting the links of the pairs, whereby to cause corresponding angular displacements of the links of both pairs.

2. In combination, a vehicle body and an axle arranged thereunder, pairs of links, the links of each pair being pivotally connected with one another and with the vehicle body and said axle, the pivotal connection between the links of one pair and the body and axle being displaced with respect to the pivotal connections between the links oi the other pair and said body and axle, and means connecting the links of the pairs, whereby to cause corresponding angular displacements of the links of both pairs, and spring means associated with said links.

In combination a vehicle, an axle, pairs of links, means pivotally connecting the links of each pair together and also with the body and axle, the pivotal connections between the links of one pair with the body and axle being displaced with respect to the pivotal connections between the links of the other pair and said body and axle, and intermeshing gear teeth carried by the adjacent extremities of the links of the respective pairs adapted to cause the latter to undergo corresponding angular displace ment.

l. In combination, a vehicle, an axle, pairs of links, means pivotally connecting the links of each pair together and also with the body and axle, the pivotal connections between the links of one pair with the body and axle being; displaced with respect to the pivotal connections between the links of the other pair and said body and axle, and intermeshing gear teeth carried by the archasignerl my name.
